Description

Technical Field

[0001] The present invention relates to the technical field of crop planting and breeding mid-row harvesting equipment, and in particular to a row divider and a wheat single-row independent harvester. Background Art

[0002] Crop breeding is the process of applying existing genetic and variation theories to practice to create new varieties through artificial selection, hybridization, and targeted breeding. It uses a variety of breeding methods to select high-yield, stable-yield, and high-quality varieties, which plays an important role in increasing crop yield, improving quality, and improving the efficiency of agricultural resource utilization. The breeding of tall crops uses planting fields dedicated to experiments for breeding. Conventionally, a single ear is a piece of breeding material. After planting is completed, the ear needs to be harvested and separated for subsequent trait research. During the harvesting process, tall crops will fall to the surrounding areas to a certain extent, especially in the breeding and harvesting operations of wheat samples. There will be straw or ears interlaced between rows, which will result in a certain amount of ears from other rows being brought in when harvesting with a harvester, resulting in impure sample species and low accuracy of research data, which affects the progress of breeding work.

[0003] In view of this, the present invention is designed to solve the above problems.

[0004] The above content is only used to assist in understanding the technical solution of the present invention and does not mean that the above content is the closest prior art. Summary of the Invention

[0005] The object of the present invention is to solve the above-mentioned deficiencies and provide a row divider and a single-row independent wheat harvester.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] The row separator comprises a central rotating wheel, a plurality of separating rods evenly distributed on the central rotating wheel for separating the interleaved portions of crops between rows, and a driving motor for driving the central rotating wheel to rotate.

[0008] Furthermore, the separating rod is hollow and is divided into two groups of shell cylinders that can be opened in half. The central rotating wheel is provided with a movable frame located inside the separating rod for supporting the shell cylinders. The central rotating wheel is provided with a first driving component for driving the movable frame, so that the central rotating wheel drives the shell cylinders to periodically expand and close during rotation.

[0009] Furthermore, the movable frame includes an inner support tube arranged on the center rotating wheel, an inner support frame arranged on the center rotating wheel, two sets of bidirectional threaded screws rotatably arranged on the inner support frame and connected to the center rotating wheel for coaxial rotation, a threaded sleeve plate threadedly sleeved on the bidirectional threaded screw for reciprocating movement, and a connecting arm hingedly arranged between the threaded sleeve plate and the shell cylinder; a first limiting sliding groove for limiting sliding of the connecting arm is provided on the inner support tube; a limiting sliding rod with one end arranged on the center rotating wheel and the other end arranged on the inner support frame is also movably connected to the threaded sleeve plate.

[0010] Furthermore, the central rotating wheel includes a fixed wheel and a movable wheel which are rotatably connected to each other, wherein the movable wheel is transmission-connected to the driving motor, and the picking rod is arranged on the movable wheel; the first driving assembly includes a full toothed disc fixedly arranged on the fixed wheel and a first gear arranged at the end of the bidirectional threaded screw and meshing with the full toothed disc; the first gears on the bidirectional threaded screw located in the same group of picking rods are meshed with each other.

[0011] Furthermore, a swing mechanism corresponding to each set of picking rods is also provided in the central rotating wheel, which is used to drive the shell cylinder to swing circumferentially with the axis of the inner support cylinder as the center when the shell cylinder is unfolded; the inner support cylinder is passed through the movable wheel and connected to its bearing, and the threaded sleeve includes an inner sleeve threaded on the bidirectional threaded screw and an outer sleeve rotatably sleeved on the outer surface of the inner sleeve, wherein the limiting slide rod is movably connected with the inner sleeve, and the connecting arm is hinged on the outer sleeve; the swing mechanism includes a swing assembly arranged on the movable wheel and forming a transmission between the inner support cylinder and a second drive assembly arranged in the central rotating wheel for driving the swing assembly.

[0012] Furthermore, the swing assembly includes a limit rail frame fixed on the movable wheel, a limit slider that slides in a limit position within the limit rail frame, a connecting frame arranged on the limit slider, a limit plate arranged at one end of the connecting frame away from the limit slider, and a lifting rod that slides in a limit position within a second limit slot arranged on the inner support tube and opened on the limit plate.

[0013] Furthermore, the second drive assembly includes a residual toothed disc fixedly set on the fixed wheel, a second gear rotatably set on the movable wheel through a bearing frame and periodically meshing with the residual toothed disc, a third gear set on the second gear and rotating coaxially therewith, a fourth gear rotatably set on the movable wheel through a bearing frame and meshing with the third gear, a crankshaft set on the fourth gear and a connecting rod rotatably set on the crankshaft; the limiting slider is provided with a fixed rod rotatably connected to the end of the connecting rod away from the crankshaft.

[0014] A single-row independent wheat harvester includes a harvester body and a straw digger arranged at the front end of the harvester body, and also includes a row divider; the central rotating wheel is arranged on both sides of the straw digger and rotates independently relative to the straw digger, and the driving motor is arranged on the harvester body, wherein the driving motor transmits power to the central rotating wheel through a transmission belt; the fixed wheels are fixedly arranged on both sides of the straw digger.

[0015] Compared with the prior art, the beneficial effects of this solution are as follows: the present invention sets a central rotating wheel and a picking rod, so that the rotation of the central rotating wheel can make the picking rod separate the crops between rows, so that when harvesting crop samples, other adjacent rows will not be harvested. At the same time, a single set of picking rods is set in the form of two sets of shelling cylinders, so that when picking crops, it can also generate lateral thrust on the straw through the expansion of the shelling cylinder, ensuring that the separation is stable and thorough, and the harvested samples will not be mixed, thereby improving the accuracy of the test.

[0016] By setting the central rotating wheel on both sides of the wheat plow and allowing it to rotate independently relative to the wheat plow, and evenly distributing picking rods on the central rotating wheel, the harvester body cooperates with the row divider to use the picking rods to pick out the wheat parts that are staggered between rows when harvesting wheat, thereby ensuring the purity of single-row wheat sample collection and greatly improving wheat breeding research and testing technology.

[0036] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] like Figure 1-17 The row divider shown includes a central rotating wheel 2, a plurality of groups of picking rods 21 evenly distributed on the central rotating wheel 2, and a drive motor 22 arranged on the harvester body 1, wherein the row divider can be assembled on a wheat harvester to be assembled into a single-row independent wheat harvester. The single-row independent wheat harvester includes a harvester body 1 and a straw digger 11 arranged at the front end of the harvester body 1, the central rotating wheel 2 is arranged on both sides of the straw digger 11 and rotates independently relative to it, the drive motor 22 is arranged on the harvester body 1, wherein the drive motor 22 is transmitted to the central rotating wheel 2 through a transmission belt 23, and the electrical signal of the drive motor 22 is connected to the harvester body 1. When the harvester body 1 is started for single-row harvesting, the drive motor 22 is started synchronously and drives the central rotating wheel 2 to rotate through the transmission belt 23. During the rotation, the central rotating wheel 2 moves upward through the picking rod 21, thereby picking out the staggered parts of the wheat between the rows, so that the straw digger 11 will not pull part of the wheat from the adjacent rows together when digging the wheat backward, thereby ensuring the purity of the collected sample.

[0038] In one embodiment, the picking rod 21 is hollow and is divided into two groups of shell cylinders 3 that can be opened in half. A movable frame for supporting the shell cylinder 3 is provided on the central rotating wheel 2, and a first driving component for driving the movable frame is provided inside the central rotating wheel 2, so that the central rotating wheel 2 drives the shell cylinder 3 to expand and close periodically during the rotation process. The expansion of the shell cylinder 3 can make the picking rod 21 produce a lateral thrust on the straw part of the wheat when picking the wheat, thereby increasing the separation distance of the wheat, and ensuring that in the process of plowing the wheat by the wheat picker 11, no part of the wheat in the adjacent rows will have an interlaced point with the wheat in the collecting row, so that the effect of separating the wheat is better and more thorough.

[0039] In one embodiment, the movable frame includes an inner support tube 4 arranged on the central rotating wheel 2, an inner support frame 41 arranged on the central rotating wheel 2, two groups of bidirectional threaded screws 42 rotatably arranged on the inner support frame 41 and connected to the central rotating wheel 2 for coaxial rotation, a threaded sleeve 43 threadedly sleeved on the bidirectional threaded screw 42 for reciprocating movement, and a connecting arm 44 hingedly arranged between the threaded sleeve 43 and the shell cylinder 3; a first limiting sliding groove 45 for limiting the sliding of the connecting arm 44 is provided on the inner support tube 4; a limiting sliding rod 46 with one end arranged on the central rotating wheel 2 and the other end arranged on the inner support frame 41 is also movably connected on the threaded sleeve 43, by driving the two coaxial groups of bidirectional threaded screws 42 to rotate, thereby making the threaded sleeve 43 on the bidirectional threaded screw 42 move relative to each other, and the threaded sleeve 43 will drive the shell cylinder 3 to expand and close through the connecting arm 44 during the movement.

[0040] In one embodiment, the central rotating wheel 2 includes a fixed wheel 5 and a movable wheel 51 that are rotatably connected to each other, wherein the movable wheel 51 is transmission-connected to the driving motor 22, the picking rod 21 is arranged on the movable wheel 51, and the fixed wheel 5 is fixedly arranged on the mounting frames on both sides of the plow 11, and it does not rotate synchronously with the plow 11; the first driving assembly includes a full toothed disc 52 fixedly arranged on the fixed wheel 5 and a first gear 53 arranged at the end of the bidirectional threaded screw 42 and meshing with the full toothed disc 52; the first gears 53 on the bidirectional threaded screw 42 located in the same group of picking rods 21 are meshed with each other, and when the driving motor 22 drives the movable wheel 51 to rotate through the transmission belt 23, the bidirectional threaded screw 42 arranged on the movable wheel 51 will drive the first gear 53 at its rear end to mesh with the full toothed disc 52 The shelling cylinder 3 is fully extended when the first gear 53 is rotated halfway on the full toothed disk 52, and is fully closed when the first gear 53 is rotated halfway. As a result, the shelling cylinder 3 at the upper end of the picking rod 21 completes a circle of circular motion, and the initial expansion and full closure of the shelling cylinder 3 are set at the meshing point of the first gear 53 and the bottom end of the full toothed disk 52, so as to maximize the expansion position of the shelling cylinder 3 to be below the interlaced part of the wheat that is about to enter the rows. As a result, when the picking rod 21 rotates toward the interlaced point of the wheat, the expansion degree of the shelling cylinder 3 will gradually increase, forming a picking and pushing action, so that the wheat can be stably separated.

[0041] In one embodiment, a swing mechanism corresponding to each group of picking rods 21 is further provided in the central rotating wheel 2, which is used to drive the shell separation cylinder 3 to swing circumferentially within a certain range with the axis of the inner support cylinder 4 as the center when the shell separation cylinder 3 is unfolded; the inner support cylinder 4 passes through the movable wheel 51 and is connected to its bearing, and the threaded sleeve 43 includes an inner sleeve 6 threadedly sleeved on the bidirectional threaded screw 42 and an outer sleeve 61 rotatably sleeved on the outer surface of the inner sleeve 6, wherein the limiting slide 46 is movably connected with the inner sleeve 6, and the connecting arm 44 is hingedly provided on the outer sleeve 61; the swing mechanism includes a sleeve provided on the movable wheel 51 and formed between the sleeve and the inner support cylinder 4 The transmission swing assembly and the second drive assembly arranged in the central rotating wheel 2 for driving the swing assembly, utilize the design of making the shelling cylinder 3 swing synchronously when it rotates and unfolds, so as to imitate the stirring action when people separate wheat by hand. This action imitation can make the wheat separation process more gentle. The swing of the shelling cylinder 3 intermittently stirs the wheat straw on its side, so as to better gradually separate the wheat that is more closely intertwined, thereby avoiding the situation where some wheat grains on the adjacent rows of wheat are separated and mixed with the wheat in the collection row due to hard separation, further improving the collection accuracy of single-row samples.

[0042] In one embodiment, the swing assembly includes a limit rail frame 7 fixed to the movable wheel 51, a limit slider 71 that slides within the limit rail frame 7, a connecting frame 72 provided on the limit slider 71, a limit plate 73 provided at the end of the connecting frame 72 away from the limit slider 71, and a lifting rod 75 that slides within a second limit slot 74 provided on the inner support cylinder 4 and opened on the limit plate 73. When the limit slider 71 moves within the limit rail frame 7, it will drive the second limit slot 74 to move back and forth synchronously through the connecting frame 72, and then the limit plate 73 will drive the lifting rod 75 to move. It is fixed on the inner support tube 4, so that the inner support tube 4 swings within a certain range. At the same time, the limit plate 73 slides in the second limit slot 74. When the inner support tube 4 swings, it drives the connecting arm 44 to rotate synchronously through the first limit slot 45 set at the upper end, thereby driving the split shell tube 3 to swing. At the same time, the inner support tube 4 has a relative sliding arrangement with the outer sleeve plate 61 and the inner sleeve plate 6 inside the inner support tube 4, so that the inner support tube 4 will not drive the inner sleeve plate 6 to rotate when it swings, so that the two-way threaded screw 42 rotates to drive the inner sleeve plate 6 to move and drive the split shell tube 3 to expand and close, and its swinging action does not affect each other and can be performed synchronously.

[0043] In one embodiment, the second driving assembly includes a residual toothed disc 8 fixedly mounted on the fixed wheel 5, a second gear 81 rotatably mounted on the movable wheel 51 through a bearing frame and periodically meshing with the residual toothed disc 8, a third gear 82 mounted on the second gear 81 and coaxially rotating therewith, a fourth gear 83 rotatably mounted on the movable wheel 51 through a bearing frame and meshing with the third gear 82, a crankshaft 84 mounted on the fourth gear 83, and a connecting rod 85 rotatably mounted on the crankshaft 84; a fixing rod 86 rotatably connected to an end of the connecting rod 85 away from the crankshaft 84 is provided on the limiting slider 71. When the movable wheel 51 rotates, its upper end The second gears 81 of different groups will periodically mesh with the residual tooth disk 8 in sequence. When they mesh with the residual tooth disk 8, the second gear 81 drives the third gear 82 to rotate synchronously by rotating. The third gear 82 transmits to the fourth gear 83, so that the crank shaft 84 on it rotates with the axis of the fourth gear 83 as the center of the circle, and then drives the limiting slider 71 to reciprocate in the limiting rail frame 7 through the connecting rod 85, thereby driving the shell cylinder 3 to swing through the reciprocating activity of the limiting slider 71, and the position of the residual tooth disk 8 is set to mesh with the second gear 81 only after the shell cylinder 3 is expanded to a certain extent, so as to ensure that the shell cylinders 3 will not affect each other when swinging.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced therein.
